【 摘 要 】

This work was conducted at the Plant Science Departament Eliseu Maciel Agronomy College of Federal University of Pelotas, in greenhouse with intermitent mist, aiming to evaluate the effect of indolebutyric acid and ethephon (2-chloroetyl phosphonic acid) on peach hranch cutting rooting. Median cuttings with 15cm length removed from Diamante cultivar branch were used. Two lateral lesions were made on cutting basis and they were treated with indolebutyric acid in liquid at 0; 1000; 2000; and 3000ppm concentrations and ethefon at 0; 50; 100 and 150ppm concentrations. The immersion time was five seconds and the cuttings were packed in polietylene sacks containing a mixture of sand and rice husk ash substrate (2:1 v/v). Results showed that the indolebutyric acid increased the rooted cuttings percentage up to 1752ppm concentration and the number of roots until 1791ppm concentration. The ethephon did not show significant variation for the form and concentrations used.
